Measuring Neck Morphologies Using Upright Magnetic Resonance Imaging, Narayan Yoganandan, Mahmudur Rahman, Ali Warriach, Karthik Banurekha Devaraj, Brian D. Stemper, Aditya Vedantam, Christopher Wolfla, Peter Le

Biomedical Engineering Faculty Research and Publications

Introduction

Because the head supported mass worn by military pilots adds loading to the head-neck complex, morphometrical characteristics of neck muscles are expected to be different from those that do not wear the added mass. To accurately determine segmental neck loads using computational whole-body human or head-neck models, it is important to include accurate morphometrical properties of cervical muscles from the population of interest, in this case military pilots. Routine radiographic imaging (x-rays and computed tomography scans) is less optimal, while magnetic resonance imaging (MRI) is appropriate. Although MRI scanners are generally available in clinical settings, recumbent scanning does not …

Linking Core Concepts And Competencies In General Chemistry Via Gowin’S Theory Of Learning And Vee Heuristic, Vijay Vyas, Scott A. Reid

Chemistry Faculty Research and Publications

The content in introductory science courses has often been criticized as “miles wide and inches deep”. In general chemistry, several revisions have focused on framing around a set of core or anchoring concepts, and we recently adapted the anchoring concepts content map (ACCM) of the American Chemical Society (ACS) to develop an anchoring concept-based curriculum for our general chemistry courses. In this article, we describe efforts to connect this curriculum with laboratory learning using Gowin’s theory of learning and the associated knowledge Vee heuristic. Within this framework, the laboratories themselves become events connecting the conceptual and methodological domains, …

Comparative Analysis Of Postoperative Visual Outcomes Of Light-Adjustable Lens, Toric Monofocal, And Spherical Monofocal Intraocular Lenses, Marisa Nakagama, Dhruv Nagesh, John F. Doane

Student Publications

This retrospective study compares postoperative visual outcomes among 150 eyes treated with Light-Adjustable Lenses (LAL), toric monofocal lenses, and spherical monofocal lenses at Discover Vision Centers in Missouri and Kansas. The study included individuals with an average age of 68.9 years (25-82 years) who had cataract extraction (CE) within the past five years. Patients with prior corneal refractive procedures, including Radial Keratotomy (RK), Photorefractive Keratectomy (PRK), Laser-Assisted In Situ Keratomileusis (LASIK) or Small Incision Lenticule Extraction (SMILE) were excluded. Sixty-four percent of eyes with LALs achieved uncorrected distance visual acuity (UCDVA) better than 20/20 after the final lock-in, 46.0% with …

Enhancing Hip And Knee Arthroplasty Outcomes With Immunonutrition: A Review Of The Evidence, Kyle Taylor, Winifred Chijoke, Quinci Howard, Sandra Messiha, Jocelyn Hunt, Bernice Diaz, Hamza Khalid, Janae Rasmussen

Student Publications

Total hip and knee arthroplasty are common surgical procedures aimed at improving mobility and quality of life. Despite surgical advances, postoperative complications remain a concern, particularly for patients with comorbidities and poor nutritional status. Immunonutrition, the targeted administration of nutrients that modulate inflammation, such as arginine, omega-3 fatty acids, and antioxidants, has been shown to reduce infections, complications in wound healing, and shorten hospital length of stay. This review examines current evidence on the role of immunonutrition in hip and knee arthroplasty, focusing on the mechanisms of key nutrients, clinical application of supplementation, and areas for future investigation. Despite promising …

Massachusetts' Latino Population: 2020-2040, Phillip Granberry

Gastón Institute Publications

Latinos have been a vital component of Massachusetts’ population growth since 1990. Their younger age structure has helped to offset the older age structure of the much larger non-Latino White population. As Latinos’ population crosses the 1 million threshold by 2030, their growth (even as it slows) will be faster than the commonwealth’s overall population change.

Latinos In Massachusetts Selected Areas: Boston, Phillip Granberry, Florita Coto Tristán

Gastón Institute Publications

The City of Boston Planning Department has found that Boston’s population was undercounted in the 2020 Census by as many as 25,000 people and that subsequent population estimates continue to understate the population.1 The Planning Department’s Research Division has developed a tool to display limited demographic data, but these population estimates are insufficient for purposes of this report.2 Therefore, this report uses 2019-2023 American Community Survey and may therefore undercount Boston’s population. Boston, the largest city in the Commonwealth, is home to an estimated 126,647 Latinos. This is the largest Latino population in the state, though other smaller cities (Lawrence, …

Noncontact Diffuse Optical Imaging Of Blood Flow And Oxygenation Distributions In Reconstructive Rat Skin Flaps, Samaneh Rabienia Haratbar, Fatemeh Hamedi, Mehrana Mohtasebi, Faraneh Fathi, Faezeh Akbari, Dara Singh, L. I.U. Xuhui, Li Chen, Lesley Wong, Lei Chen, Guoqiang Yu

Surgery Faculty Publications

Perioperative identification of ischemic-hypoxic tissue is essential for reducing the risk of mastectomy skin flap necrosis (MSFN), a major complication following mastectomy. Implant-based breast reconstruction is jeopardized in the presence of MSFN. However, existing technologies are limited by depth insensitivity, dye-related risks, the need for contact sensors, and an inability to simultaneously assess both blood flow and oxygenation. A multi-wavelength speckle contrast diffuse correlation tomography (MW-scDCT) system was developed for noncontact, dye-free, and depth-sensitive imaging of tissue hemodynamics in a rat model incorporating four distinct flap scenarios: sham (SH), implant (IM), half necrosis (HN), and full necrosis (FN), representing varying …

Microwave Ablation For Hepatocellular Carcinoma In Cirrhotic Patients With Diuretic-Resistant Ascites, Sawyer Blair, Jack Newcomer, Driss Raissi

Surgery Faculty Publications

Objectives: The purpose of this study was to evaluate the feasibility, safety, and efficacy of computed tomography (CT)-guided percutaneous microwave ablation (MWA) of liver hepatocellular carcinoma (HCC) lesions in patients with pre-existing diuretic-resistant ascites. There is logical hesitation among clinicians to pursue MWA in these decompensated patients for fear of worsening an already bleak prognosis, but there is limited evidence to justify this behavior. Material and Methods: A retrospective review of HCC treated with percutaneous MWA at a single center was performed. 18 patients who underwent CT-guided MWA with pre-existing diuretic-resistant ascites were identified. A control group of 29 patients …

Background: Hip fractures are common in older people and are associated with high perioperative mortality. Prompt surgical intervention within the first 48 h of fraction reduces complications; however, surgical urgency often precludes a comprehensive preoperative cardiac evaluation. Preliminary data suggests that performing a focused cardiac ultrasound (FCU) before surgery may reduce postoperative complications. We therefore propose to test the primary hypothesis that FCU reduces a 30-day composite of mortality and serious complications.

Methods: We plan a definitive multicenter pragmatic randomized trial that will enroll 2000 adults with hip fractures. Participants will be randomized before surgery to either receive FCU as …

Polygenic scores (PGSs) for body mass index (BMI) may guide early prevention and targeted treatment of obesity. Using genetic data from up to 5.1 million people (4.6% African ancestry, 14.4% American ancestry, 8.4% East Asian ancestry, 71.1% European ancestry and 1.5% South Asian ancestry) from the GIANT consortium and 23andMe, Inc., we developed ancestry-specific and multi-ancestry PGSs. The multi-ancestry score explained 17.6% of BMI variation among UK Biobank participants of European ancestry. For other populations, this ranged from 16% in East Asian-Americans to 2.2% in rural Ugandans. In the ALSPAC study, children with higher PGSs showed accelerated BMI gain from …

Faculty, Staff and Student Publications

Introduction: Little is known about change in sleep duration over time and Alzheimer's Disease and Related Dementias (ADRD) risk.

Methods: ADRD cases were identified among Southern Community Cohort Study participants enrolled in Medicare. Sleep duration was reported at enrollment and first study follow-up and categorized (short (< 7 hours), recommended (7-9) and long (> 9)), change was calculated between timepoints. Adjusted Cox proportional hazards regression was used to estimate hazard ratios (HRs, 95% CIs) for incident ADRD.

Results: We identified 2,093 ADRD cases among 17,945 participants. Compared to maintaining optimal sleep duration (7-9 hours) over 5 years, suboptimal changes were associated with 20-69% greater ADRD risk: adjusted …

Background: Excessive daytime sleepiness (EDS) is a complex sleep problem that affects approximately 33% of the United States population. Although EDS usually occurs in conjunction with insufficient sleep and other sleep and circadian disorders, recent studies have shown unique genetic markers and metabolic pathways underlying EDS. Here, we aimed to further elucidate the biological profile of EDS using large-scale single- and pathway-level metabolomics analyses.

Methods: Metabolomics data were available for 877 metabolites in 6071 individuals from the Hispanic Community Health Study/Study of Latinos (HCHS/SOL). EDS was assessed using the Epworth Sleepiness Scale (ESS) questionnaire. We performed linear regression for each …

cAMP influences multiple aspects of cardiac biology, including the regulation of contraction, relaxation, and overall stress responses. The functional outcomes of cAMP are driven by the spatial arrangement of enzymes that produce and degrade cAMP (adenylyl cyclase [AC] and phosphodiesterase, respectively), together with the downstream targets of cAMP. We performed proximity-dependent biotin identification (BioID) of near-neighbor interactions proteomics in cardiomyocytes to generate proximity maps for three cardiac AC isoforms. Processing and trafficking functions were the most common gene ontology terms for ACs, with AC5 and AC6 generating unique proximal protein sets compared to AC9. AC5/6 proximal proteins showed significant localization …

Objectives: The US Food and Drug Administration (FDA) issued a warning about buprenorphine-induced dental caries of unknown mechanism in 2022. To investigate the potential mechanism, the association between local buprenorphine exposure and dental biofilm formation will be explored in this study.

Methods: Female F344 rats were dosed with sublingual buprenorphine film or intravenous injection to explore the oral cavity exposure of the buprenorphine. The buprenorphine distribution in salivary glands after the sublingual and intravenous administration was also evaluated. To investigate the effects of buprenorphine exposure on dental caries formation, buprenorphine's impact on the biofilm formation of S. mutans in vitro …

Women's Unique Health Needs And The Sustainable Development Goals: A Meeting Report From The 79th United Nations General Assembly Science Summit, Irene Aninye, Sarah Chew, Nicole Althaus, Michele Barry, Ru-Fong Cheng, Carolyn Harris, Eleanor Nwadinobi, Beth Battaglino, Aisha Brooks, Marleen Temmerman

Biological sex, hormones, and gender uniquely affect health and disease, often resulting in disparities for women across the lifespan and from different racial and ethnic groups, geographical locations, and socio economic backgrounds. Without intentional investment and infrastructure to support good health and wellbeing for women,half of the world’s population remains vulnerable to preventable morbidity and mortality. The Society for Women’s Health Research and ECHAlliance–The Global Health Connector convened a women’s health programas part of the 10th Annual Science Summit during the United Nations 79th General Assembly. This hybrid event was held in New York, NY, (USA) and virtually in September …

Policy Evaluation With Nonlinear Trended Outcomes: Covid-19 Vaccination Rates In The United States, Lynn Bergeland Morgan, Peter C. B. Phillips, Donggyu Sul

Research Collection School Of Economics

This paper discusses pitfalls in two way fixed effects (TWFE) regressions when the outcome variables contain nonlinear and possibly stochastic trend components. If a policy change shifts trend paths of outcome variables, TWFE estimation can distort results and invalidate inference, especially in a context of evolving policy decisions. A robust solution is proposed by allowing for dynamic club membership empirically using a relative convergence test procedure. The determinants of respective club memberships are assessed by panel ordered logit regressions. The approach allows for policy evolution and shifts in outcomes according to a convergence cluster framework with transitions over time and …

Exploring The Contextual Antecedents Of Nonfamilial Aggression In Women Arrested For Aggressive Behavior, Tatiana Pouncy

Walden Dissertations and Doctoral Studies

The prevalence of physical aggression among women has increased, challenging traditional gender norms that portray women as nurturing and nonviolent. While most research on aggression has focused on men, children, or intimate partner violence, research is sparse concerning female aggression outside familial contexts. In this qualitative multiple-case study, the contextual antecedents of nonfamilial aggression in women arrested for aggressive behavior were explored using the general aggression model as the theoretical framework. Data were obtained from 20 publicly documented cases using archival sources such as media stories, court documents, and video recordings. According to thematic and document analysis, aggressive behavior was …

Exploring The Lived Experiences Of Former Lagos State Male Public High School Teachers About Their Onboarding Process., Agboola Clement Ikuyinminu

Walden Dissertations and Doctoral Studies

Lagos State, Nigeria, faces male teacher retention challenges in public high schools, including destabilizing the educational environment, reducing the availability of experienced mentors, and negatively impacting student performance and outcomes. School leaders need to understand the challenges leading to male teacher turnover. The purpose of this qualitative phenomenological study was to explore the lived experiences of Lagos State male public high school teachers who left the profession, focusing particularly on their perceptions of onboarding and reasons for leaving the profession. This study was grounded in Herzberg’s two-factor theory, Bauer and Erdogan’s onboarding theory, Maslow’s hierarchy of needs, and Bandura’s social …
